  • Publication number: 20070228753
    Abstract: An elevator apparatus and method. The apparatus includes a circular member comprising a first and second semi-circular half and a hinge pin(s) for pivoting the first and second semi-circular half together. The elevator apparatus further includes a hinge rotary actuator(s) for activating the hinge pin(s) so that the first and second semi-circular half pivot to form the circular member, a latch rotary actuator for latching the first semi-circular half and the second semi-circular half. In one preferred embodiment, the hinge rotary actuator(s) comprises: a first cylinder; a first rack disposed within the cylinder, the first rack being responsive to a pressure within the cylinder; and a first roller having teeth disposed thereon, wherein the first rack and the teeth are engaged and wherein the roller is connected to the hinge pin.
